JOHN OOCKBURN, OF NEW YORK, N. Y.

Y PEN AND PENCIL CASE.

Speciiication forming part. of Letters Patent No. 27,777, dated April 10, 1860.

To all'whom it may concern.

Be it known that I, JOHN CocKBURN, of the city, county, and State of New York, have invented a new and improved Pen and PencilCase; andl do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specication, in which- Figure 1 is a longitudinal sectional view of my invention with the pencil shoved out from the case; Fig. 2, an enlarged longitudinal section of the same in an extended state, with the pen shoved out from the case.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a pen and pencil case that may be closed within a small compass to admit of beingreadily carried in the pocket and still be extended `sufficiently when required to form a handle vof requisite length for convenient use.

The invention consists in combining with an ordinary spirally-slotted tube for operating the pencil-tube, an extension-tube and pen-slide, all arranged relatively with each other and fitted within a shell or external case, as hereinafter shown and described, to effect the desired end.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the shell or external case of the pencil, which may be of cylindrical or ,other suitable form, andB represents an extension slide or tube which is a trifle smaller in diameter than the case A, so that the former may slide freely into and not from the latter. The tube B has, a reserve d for leads in its outer'ends. v Y l The interior of the extension-tube B has a tube b secured permanently to it. This tube b is slotted longitudinally at the opposite points of its periphery, as shown at c d. The tube b is iitted on and works over a central tube C, which is permanently and concentrically secured within the case A, as shown at e, Fig. 2, suliicient space being allowed between the case A and tube C to admit of the extension-tube B and its inner tube b to slide freely into and out from the case A.

Within the tube C there is secured perm-a recess k.

nently and concentrically a tube D, f being the point of connection. This tube D is slotted spirally, as shown at g, and is iitted on a tube E, which contains an ordinary pencil-slide F. The tube E extends to the orifice of the case A, and is connected with a collar h, within which the end of the tube C is fitted and allowed to turn freely.

Between the tubes Oand E a pen holder or slide G is fitted and allowed to work freely back and forth. attached to it, which pin passes through a longitudinal slot j in the tube C, as shown clearly in Fig. 2. The pin t' projects a short distance through the slot j, sufficiently so to pass into the slot c of tube b when the latter is shoved inward. The slot c has a short side recess lc in it near its end.

To the tube D near its upper end apin Z is attached, and this pin projects through the tube C and into the slot dof tube b, and to the pencil-slide F a pin 'm is attached, said pin itting in the spiral slot g of the tube D.

The operation is as follows: By turning the case A the pencil-slide F is shoved out from or drawn within the tube E, and this operation is eifected with the tube B either in or out of the case A. This movement is eected in consequence of the connection of the case A and tubes C D, the spiral slot g acting against the pin m of the pencil-slide, while the tube E is prevented from turning in consequence of the collar hbeing held by the operation while turning the case A. The eX- tension-tube B is made to operate the penslide G by turning it in the case A, for instance. lf the tube B is within the case A, and also the pen-slide G, and it is desired to shove out the pen, the tube B is rst drawn directly outward until stopped by the pin l.

Said tube B is then turned from right to left, so that the pin m may be fitted in the side The tube B on being shoved into case A will throw or force out the pen# slide, and the tube B is then turned fromleft to right to free the pin m from the recess 7c and drawn outward again to form the extension. To draw the pen-slide within the case A, the tube B is shoved into the case, turned from right to left to allow the pin m to lit in the recess 7c, and then drawn outward, the penslide being thereby drawn within the case.

The pen-slide has a pin t',

2 www The tube B is then turned from left to right to free the pin m from' the recess lo, and the tube B shoved into the oase A.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the spi rally-slotted tube D, extension-tube B, the longitudinally-slotted tubes b C, and the tube E with the pencilslide F and pen-slide G, the pencil-slide F,

pen-slide G, and the tube D being provided, respectively, with pins m z' Z, which fit in the slots g o d of the Lubes D C, and all arranged relatively with each other and the oase A as and for the purpose specified.
